1b all rcito/iz 'it may concern.'

Be it known that l, .REUBEN P. GRANT, a citizen oll the United States7 and a resident ot' Manchester, county of Hillsborough, and `tate ot New `Hampshire, have invented certain new and useful improvements in Counter-Skiving Machines, of which the following is a specication, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to an improved machine for producing from a strip or strips of material Aliat counters suitabl f shaped and skived for use in the manufacture of boots and shoes, as said counters are delivered Jfrom this machine, or adapted to be molded or operated upon in any known and desirable manner prior to their incorporation in boots or shoes.

One object of the invention. is to provide boot and shoe counters ouniform shape having beveled or skived edge portions substantially similar in all counters, which beveled portions or surfaces extend from the original surface ot the counter blank substantially without irregularities of a character to render a shoe having the improved counter uncomfortable in this respect.

Another object of the invention is to provife a counter machine wherein counter blanks brought to position can be supplied .troni such position alternately to each of a plurality of counter skiving devices whereby the output of the machine may be increased without unduly increasing the speed oi' the skiving appliances or cutters.

nother object ot' the invention is to provide a machine of the nature described by which counter stock material in strips may be received by the machine; severed to constitute counter blanks each having a short edge and a long edge and the short edges and the ends oit said blanks skived or beveled v-ithout unduly limiting the operation of the stock severing means.

.lli'iother object of the invention is to iinprove the counter skiving` means whereby thc skiving or cutting devices are operated in sweepin and opposite directions relative lo the longitudinal center oi2 the blanks.

Another object of the invention is to improve the waste discharging means.

Other objects of the invention will appear from the following description.

The invention consists in the organized means whereby the counter stock or material supplied to the machine is selvered into counter blanks and said blanks are carried alternately to one of a plurality of skiving,` devices, are there skived and are linally delivered from the machine.

The invention also consists in the novel means for supplying the counter blanks to the blank holders for the skiving devices; in the means for holding or clamping' said blanks to present their edges to the skiving devices, and in the skiving devices and means for operating the same.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Like characters of reference designate corresponding parts throughout.

The machine illustra-ted in the drawings and hereinafter described lis intended and adapted to receive a strip 0r strips of leather board or other counter stock of material, of a desired Width and of any length adapted to be supplied tothe machine kwhich strip or material S is operated upon by elements of themachine; 'first to divide or sever said strips to provide a progressing series of counter blanks; second 'to take such blanks in succession 'from the line of their initial direction to devices for conforming, adjusting and holding said blanks during the skiving voperation and for facilitating such operation, and finally for delivering the counters from the machine and for discharging the scrap material removed from the blank in the skiving operation.

lVithout thereby limiting this invention I prefer to use strips of stock similarto that shown in Fig. 17 Vhaving one or both of its edges beveled as Shown in said Fig. 17 and also, on larger scale in Fig. 20, but it is evident that said edge or edgesneed not necessarily be beveled and in some cases I may prefer to use strips of stock yhaving rectangular edges or Vedges of any desired and suitable shape.

The term counter used herein is intended to refer to the product of this iinproved machine as such product is adapted to be used as va counter for a boot or slice by the simple bending or other manipulation of said product to incorporate the saine in a boot or shoe structure. lt is evident rhowever that the counter constituting the product of vthis machine may be operated upon lin lany desired manner as by molding, crimping or otherwise.

Said blocks 151 are adjustably mounted on the cross bars 168, 163, and are secured by set screws 164-.

Said cross bars 163, 163 connect the inner ends of each pair of parallel slide rods 165, 165 which are mounted to slide in blocks 166, 166 mounted on rock shafts 167, 167 supported in bearings on brackets 16S, 168 pro jecting upwardly from the left hand and right hand ends of bed 29. rllhe arms 1'7 0, 170 arc secured on the ends of said rock shafts and are connected to the respective cani icvers 171 and 172 by the links 173. (Figs. 1 and Cain lever 171 is pivoted on shaft and its outer arm is furnished with can'. roll 171 whieh engage` the groove in cylinder cani carried by the upright shaft Cani lever 172 is pivoted on shaft 177, coi csponding to said shaft 12S, and its outer end is provided with cani roll 173 which engages the groove in cylinder cam 179 (arried by upright shaft 13.

pwardly projecting lugs 180, 180 are respectively on the rear rods of said pairs of side rods 165, 165 and are connected'to the vers 181, 181 by links 182, 182; Said vers 181 are respectively pivoted' at their lower ends on brackets 183, 183 respectively projecting from the left and right hand sides of the frame of the machine. Links 185, 185 res )ectively connect said levers 181 with the upper arm of elbow cam levers 186, 186 which are pivoted on the frame.

lhe lower arms of said cani levers are pi'ovided with cam rolls which engage the grooves in cylinder cam* 187, 187 mounted on said respective upright shafts and 36.

The left hand and right hand work releasing devices 190, 191 respectively, are mounted to travel over the top of cutting table 60, and are provided with the lower work engaging fingers 192, 192 of spring sheet metal secured to the respective ends of the forward arms of the levers 193, 193 pivoted on the ends of arms 191, 191. The upper work engaging fingers 195, 195 are pivoted on pins 196, 196 on said leve s 193, 193 and are presserL downwardly by springs 197, 197 on said pins 196, 196. The forward ends of said upper fingers 195, 195 are rounded over and tend to be swung into engagement with said lower lingers by coil springs 198, 198 connected to the rear ends of levers 193, 193. Said upper fingers 195, 195 are. provided with lugs 199, 199 adapted to be engaged. by lugs 200, 200 adjustably secured to said arms 191, which latter arms are respectively fastened on the upper ends of vertical shafts 201, 201 having their upper portions pivoted in brackets 202, 202 on the rear of bed 29, and the lower portions of said vertical shafts are pivot-ed in brackets 203, 203 on the rear side of the frame of the machine.. Links 205, 205 are pivoted at their outer ends on said bracket-s 202, 202 and their inner ends are connected to the rear ends of levers 193. The arms 207, 207 are respectively secured tol the lower ends of said shafts 201 and are connected to cam levers 209, 209 pivotedl on brackets 210, 210 by links 20S, 20S; Said cam levers are furnished* with camY rolls 211 which respectively enga-ge the groovedcams 212 and 213 carried by upright shafts 42 and 413, respectively. (1F igs. 1, 5 and 11.)

Referring again to the cutting' ofiv knife holder 107, tliesame'is provided on its front side with the laterally adjusta-bl'eV strip guides 215 consisting of the `plates 216' secure-d to holder 107 by screws 217 extending through horizontal slots in saidt plates. The upper ends of said platesv are bent inwardly toward said horizontal aperture` 109. The lower end of said knife holder 107 is provided with the arm 219 connected to elbow cam lever 220 by link 221 adapted to be' adjusted lengthwise of said arm. Cam lever 220 is pivoted on bracket`223Y secured to the underside of bed 29 and is furnished with a cani roll which engages grooved cam 225. (Figs. 1, d and 16;) i

In the operation of the machine, the usual strip of leather or leather boardfS preferably having bevel edges; is fedV between'the'cutting od knives 110 and`11'3 and over work support 117 to the gage 135; the strip'being guided and held by theV strip guides 215vand by side guide bars 138, and top guidespring 139 of said gage 135. (Figs. 1, 4, 5 and 6.) lork support 117 is then raised tothe level of cut'- ting table 60 by cam 131 through cam lever 127, beam 123, studs 121 and bar 119; The movement of said work support transmits a like movement to knife blade 11'3, through roller 116, causing"` said knife blade to cooperate witlr knife'bla-de 1-10 to cut olf the blank B from the strip S; In order to save stock and to make the blanks B more nearly conform to the shape of the finished blank, I prefer to alternately cut off the blanks from'strip S' on'oppositely inclined or diagonal lines as indicated by dotted lines in Fig. 17. This is effected by the proper oscillation of cut off knife holder 107 operatedY by Cain 225 through elbow cam lever 220, link 221` and arm 219. (Fig. 16.) The amount of inclination, of the respective cutting operations may be varied as desiredby the adjustment of link 221 lengthwise ofy arm219.

Immediately following the cutting of a blank the forward; end of the late `al feeding device 155 is swung downwardly from the forward' raisedl position shown in the drawing to cause theiingers 157. 157 to position themselves adjacent. the right hand edge of the blank and to.I cause the kpointedA ends of pins159 to be forced into'the top surface of the blank. Saiddownward engagingmovement of the forward end of saidl feeding device is effected by cam 175 through cam lever 171, link 173, arm 170 and shaft 167. (Figs.

1, 4, 5, G and 7.) Upon the completion of the latter operation, end gage 135 is drawn back out of engagement with said blank b cani 150 through Ycani lever 147, link 146, shaft 142, arm 141 and link 140. (Figs. 1 and 15.) Said feeding device 155 then carries the blank to the left hand die 77, with the base edge of blank B against stops 77 a in which position blank B is held by the fingers 157 of the particular blank feeding or transporting device 155. The blank is positioned on said die 77, beneath the inner end of the previously raised clapper 86, which, in its closing movement, forces the blank B down onto the die 77 and causes the upward deflection of the edOe portion of blank B extending beyond clapper 86. In Fig. 10 is shown the relative position of a blank on the right hand die 78, before clapper 87 is closed, which corresponds to said positioning on die 77. Said die 78 is shown as being provided with a pair of stops 78a which correspond to said stops 77a. It is understood that such lateral movement of feeding device 155 to the left is effected by cam 187, through elbow cam lever 186, link 185, lever 181, and link 182.

Following` said positioning of the blank on die 77, cam 99, through cam lever 9G, link 95, and elbow lever 92 forces Yclapper 86 to clamp the blank down onto the die; and immediately the feeding device 155 is disengaged from the blank by cam 175 through said connecting mechanism, and is returned toward its initial position by cam 187 through said connecting mechanism. When the blank is thus held down onto the die 77 by said clapper 86 the skiving devices carried by shafts 35 and 42 are brought into operation. Assuming that the skiving device of shaft 35 is swinging in the direction of the arrow on collar 48, Fig. 1, the knife of such skiving device will make the first cut, the blade, similar to blade 55, Figs. 9, 12 and 13 traveling very close to the upper surface of clapper 86 and engaging that edge portion of blank B which extends above said clapper at about the point 79 Fig. 18, taking a cut approximately from the dotted line c to the dotted line d and extending diagonally from dotted line c through the thickness of the blank B to said line d whereby the margin of blank B beyond line I is cut away. After the skiving blade engages'the material of blank B at o the course of said knife is for a time substantially lon- `gitudinal of said blank B in the direction indicated by the arrow from the lineof l), but this direction of the skiving knife is gradually changed to a curving direction the curve of which is accentuated as the skiving knife approaches the end of the blank B and finally the skiving knifeswings approximately at right angles to its first direction and cuts through the material to the base edge g of said blank B. After the skiving knife of the skiving device operated by shaft 35 has moved past line Z/ sufliciently to clear a path for the skiving device of shaft 42 the knife of this latter device engages the material of blank B at or about line and takes a cut, similar to that just above described in the general direction indicated by the arrow from said line b following substantially the dotted line d. The initial cut of this second knifeY removes any irregularities on the blank left by the first skiving operation between the lines Z) and and it is to be noted that the blank B may, to some extent, be operated upon simultaneously by both' skiving knives, provided that the carriers for said knives do notrinterfere. It will be observed that the skiving knife blades are so ground and positioned that they tend to force the blank down onto the edge of the die and that the skiving action of the knives respectively extend from approximately the center to the ends of the blank, resulting in the blank being uniformly and smoothly skived. (Figs. 19 and 21.)

The trimmings or scraps which are skived or cut from the blank by the skiving knives, are forced between the respective discharge rollers 64 and the beveled surfaces 61 of the knife blades Vand are carried thereby until they are respectively dischargedA into the chutes 64a, 64CL at the respective left hand corners of the cutting table 60. The discharge of the scraps into said chutes is effected by the downwardly projecting spring arms 73, 73a which im parta quick spin to discharge rollers 64 through the engagement of the respective pinions 73, 73 with said spring arms, whereby said scrap is given a forward impulse.

AtY the completion of the skiving of the blankon the left hand die, the fingers 192 and 195 of releasing device 190 engage the rear end of the blank, and immediately thereafter cam 99 permits spring 101 to raise clapper 86, allowingY said releasing device to release the blank from the die and discharge it into chute 190a at the rear of the machine. Said fingers of the releasing device are moved inwardly to engage the blank by cam 212 through cam lever 209, link 208,'arm 207, shaft 201, arm 194 and lever 193 which carry said fingers. As said fingers are being' moved inwardly the forward end of lever 193 is lswung away from arm 194 by link 205 which disengages lug 199 on finger 195 from lng 200 on said arm, thereby Vpermitting spring 198 to swing iinger 195 into position over linger 192 to cooperate with the latter to engage the end of the blank. As said lingers approach the limit of their rearward movement, lug 199 again engages lug 200, which .disengages linger 195 from the blank, thereby effecting .the discharge of the .blank into said chute 190% Immediately after :the first blank is fed from the work support 1.1;7 toward the vleft hand die 7T, as hereinbefoifc described, `cam 131 effects the loweringof said .worksupport and cutting Aoff k-nigfe 113 through thereuuecting mechanism, and end gage 135 is then moved Aiirward to itseffective position. The movement of said end .gage is accomplished by cani 150, cam lever 1&7, ,link vr1f6arm 145, .shaft lai-f2, arm 141,*and link `1110. (Figs. 1, 5, 6 and 15..) After said Vpositioning .of said 4end gage, vthe remainder o f the strip S is .fed into engagement ywith theend gage and vthe next blank is vout from .the .strip and is .fed .tothe right hand die .by feeding device' 15G which operates in asimilar manner A,as feeding device 155. The .blank fed @to the .fright hand die is operated `upon and finally released into right hand chute 191a tin lthe same .manner as -the `blank -ffed [to the left hand ldie which Awas final-ly released into chute 190?. i

lt is to be noted .that ,two blanks may be subjected vvto skiving operation `at .or about -theesame time and ,that before one ,ojf -said blanks .is delivered from the .machine `a third blank may iliave -been severed :from the strip vS and may be .ready for .an Aapproaching :blank engaging Yand Y.transferring device 155 or 156 as vthecase may be.

It will be seen that dies o f various .sizes maybe used .on the .machine and the operative Yparts of the y'machine correspondingly adj usted `to effect the cutting voff and .skiving of a variety -ofsizes of counter blanks.

Having .thus described my invention .I claim as new -anddesire tosecure by Letters Patent:
